Abstract

The invention provides a log data synchronization method and device, a server and a storage medium, and the method comprises the steps of generating first log data, writing the first log data into thefirst storage medium corresponding to a main database, and synchronizing the first log data to a slave database, judging whether to send the first log data to the slave database again or not according to the receiving condition of the synchronization feedback message sent by the slave database, so as to directly synchronize the first log data to the slave database after the first log data is generated; in the first log data synchronization process, saving the time consumed for writing the first log data into the first storage medium and reading the first log data from the first storage medium, so that the synchronization time of the first log data is shortened; and sending the first log data to the slave database again under the condition that the receiving condition of the synchronization feedback message indicates that the first log data is not successfully synchronized, so as to ensure that the log data in the master database is consistent with the log data in the slave database.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a log data synchronization method, device, server and storage medium. Background technique [0002] At present, in order to ensure the security and high availability of the database, a backup library of the database is built. The database that needs to be built as the backup library is the master database, and the backup library is the slave database. The log data generated during the database writing process is sent to the slave database synchronously. The process of synchronously sending log data to the slave database is as follows: [0003] Read the log data from the disk through the thread corresponding to the master database, and send the read log data to the slave database, such as figure 1 shown. The sending thread corresponding to the master database reads the log data from the disk, and then sends the read log data to the receiving thread...
